[Postgres-xc-general] Postgresql - Postgres-XC

[Iwan S. <iwa...@ya...>]

Hi,

I am newbie and need some advice.
I read documentations but not fully understand the implementation
of postgres-xc on existing server. 

We have two computers at office, one computer runs postgresql ver 9.1 
and another computer for Apache 2.xx Web server. 
I want to make postgres cluster and add two more computers. 

My questions:
1. Should I reinstall existing DB server with postgres-xc? 
    (Is there any documentations about migration?)   
2. Should I use the same computer spec for every computer on cluster?

Thank you 

Regards,

Iwan
